Swimming in water contaminated with blue-green algae may cause symptoms of poisoning to people. Drinking water that is contaminated with blue-green algae or using it in cooking, for washing up, in the sauna or for bathing or washing may also cause symptoms of poisoning.

Symptoms: In Finland, symptoms associated with blue-green algae have been mild. The most common symptoms include abdominal symptoms, skin symptoms and flu-like symptoms. Nausea, vomiting, abdominal pain and diarrhea have been described as abdominal symptoms. Abdominal symptoms usually subside in a few days. Skin and flu symptoms develop more slowly and may last longer than abdominal symptoms. A rash, itching and stinging have been described as skin symptoms. Flu-like symptoms include a blocked or runny nose, a sore throat, a headache and fever. Blue-green algae may cause an eye or ear infection.

Treatment: Wash the exposed areas with clean water and soap. Rinse the eyes with clean water. Care at home is usually sufficient for symptoms caused by blue-green algae. If necessary, use pain relief or an antipyretic drug. If the symptoms are severe and do not disappear within a week, contact a doctor. If you develop symptoms of an eye or ear infection, you should contact a doctor.

The plant is toxic, but ingesting a small amount rarely causes symptoms.
